Mentioned in Scripture, of Eden (Gen. 2:8, 9); Ahab's garden of herbs (1 Ki. 21:2); the royal garden (2 Ki. 21:18); the royal garden at Susa (Esther 1:5); the garden of Joseph of Arimathea (Jn. 19:41); of Gethsemane (Jn. 18:1).
The "king's garden" mentioned 2 Ki. 25:4, Neh. 3:15, was near the Pool of Siloam.
Gardens were surrounded by hedges of thorns (Isa. 5:5) or by walls of stone (Pr. 24:31). "Watch-towers" or "lodges" were also built in them (Isa. 1:8; Mk. 12:1), in which their keepers sat. On account of their retirement they were frequently used as places for secret prayer and communion with God (Gen. 24:63; Mt. 26:30-36; Jn. 1:48, 18:1, 2). The dead were sometimes buried in gardens (Gen. 23:19, 20; 2 Ki. 21:18, 26; 1 Sam. 25:1; Mk. 15:46; Jn. 19:41).
